The answer is, 24x
The answers are ± 625
ok lets let x=4. The square root of 4 to the 2nd power + 4= 8. The square root and power of 2 cancel out? Is that what you mean?
x^2 = 54; take the square root of both sides, so x = +/- square root of 54 , or simplified is +/- 3 times square root of 6.
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.
square root of c to the second power is c
The answer is, 24x

Isnt that just the square root of 64, being 8...?
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.
Press 2ND and then the square root sign (above x2). Then type the number you want to find the square root of. Press ENTER to see the answer.
x^2 plus 4 = 0x^2 = -4square root both sidesx = the square root of -4x = 2i
